油页岩中微量元素赋存形态的研究
, PP. 1295-1301
Keywords: 油页岩,微量元素,赋存形态,浮沉实验,脱灰实验
Abstract:
？通过浮沉实验及脱灰实验对抚顺、龙口、茂名3种油页岩样中部分微量元素进行了赋存形态的研究.结果表明,浮沉实验所得微量元素的赋存状态结果与脱灰实验基本一致,抚顺、龙口、茂名3种油页岩中大部分微量元素以无机态赋存,但也有所区别,抚顺、龙口、茂名油页岩中的元素v、mn、zn、sr、mo、ta以及抚顺油页岩中的cr、te,龙口油页岩中的cd、sn,茂名油页岩中的cd、sn、pb,主要赋存于无机矿物中;茂名油页岩中的cr、te,抚顺油页岩中的cd,龙口油页岩中的pb有相对较多的比例富集于有机质部分;龙口、茂名油页岩中的元素co,抚顺油页岩中的co、sn、pb,更多地富集于黏土矿中,但也有少部分富集于有机质中.
